Thanks for the hint, I'll try that.

I tried to modify dependencies within edk2-platforms to explicitly
cover FaultTolerantWriteDxe.inf and gEfiCpuArchProtocolGuid, but did
not succeed.

With this patch the things work properly, but I am wondering if only
by luck. I found following line in
BaseTools/Source/Python/UPT/Xml/XmlParser.py:
DxeObj.SetDepex("gEfiBdsArchProtocolGuid AND \ngEfiCpuArchProtocolGuid
AND\n" + \
it seems not to apply for MvFvbDxe though. So simply it may be an
order of entries in Armada7k8k.fdf file.

Best regards,
Marcin
